The ESP32-CAM is a versatile and affordable camera module that can be used for various projects. In this tutorial, we’ll explore how to set up video streaming from the ESP32-CAM to Home Assistant, allowing you to monitor your surroundings remotely.
Setting Up Video Streaming Web ServerOpen the Arduino IDE and navigate to the ESP32 examples.
1. Select File->Examples->ESP32->Camera->CameraWebServer example in Arduino IDE.
2. Replace the codes in CameraWebServer with the code below (Note: please fill in your WiFi account and password)
#include "esp_camera.h"
#include <WiFi.h>
//
// WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
// Ensure ESP32 Wrover Module or other board with PSRAM is selected
// Partial images will be transmitted if image exceeds buffer size
//
// You must select partition scheme from the board menu that has at least 3MB APP space.
// Face Recognition is DISABLED for ESP32 and ESP32-S2, because it takes up from 15
// seconds to process single frame. Face Detection is ENABLED if PSRAM is enabled as well

Setting Up Video Stream PropertiesNext, open up the IP address that shows in the serial terminal and look for the camera web server properties.
Set up the resolution. Go with the lower one to get a high FPS.
Finally, add the:81/stream in the camera IP address.
Now it will directly show you the camera feed.
- Open Home Assistant.
- Next, navigate to the overview and add a picture card.
- Enter the IP address of your ESP32-CAM following:81/stream and click Finish.
- And that’s it! You’ve successfully set up video streaming from the ESP32-CAM to Home Assistant.
Feel free to customize and enhance this project further. Happy monitoring! 📷🏠
